DNA representing biology on Liechtenstein stamp

On 28 August 1969 Liechtenstein released a set of 4 stamps to celebrate the 250th anniversary of the Duchy of Liechtenstein. Each of the 4 stamps features an important field of study - biology, physics, astronomy and art. The stamp representing biology features a man and the double-helical structure of DNA. This is the earliest use of the double helix to represent science on a stamp design. Scott 454.
